Verified Purchase(What is this?)
This review is from: Bosch PMD 10 Multi Detector (DIY & Tools)
I am only an amature. I had borrowed a cheaper device (approx 1/4 the price) which sort of worked but even with multiple scans (wipes) over the area of interest it was very difficult to know accurately enough for me where it was safe to drill. The search was for electrical wires, some covered with protective steel half trunking / guard. I got the Bosch PMD 10 thinking I had better get a good device and since in the future the ability to detect battens or beams behing ceiling plasterboard was likely to be useful. The Bosch machine works much better than the cheap device I tried on my home electrical job. A quick test showed it also seemed to detect beams behing plasterboard reasonably well. To detect any material of interest one does have to use the machine intelligently and not expect magic. I have some understanding of the way the device works. I am a professional physicist and electrical engineer. It is not simple to design a machine to accurately make the detections of interest. A good too to have in ones tool box, even if you don't use it very often. What is the cost of popping an electrical cable or pipe, not to mention the resulting mess and inconvenience to put things right?
